Technik der Mesohepatektomie
2016
Bei Patienten mit einer primar oder sekundar malignen zentralen Leberraumforderung stellt die Resektion im Sinne einer erweiterten Hemihepatektomie rechts bzw. links das Standardverfahren dar. Unter Berucksichtigung der erhohten Morbiditat und Mortalitat bei erweiterten Resektionen und dem Aspekt des hohen Verlusts an gesundem Lebergewebe stellt die zentrale Leberresektion oder Mesohepatektomie (Resektion der Segmente 4a/4b, 5 und 8) mit oder ohne Resektion des Segments 1 eine technisch anspruchsvolle und weiterhin selten genutzte Alternative dar. Die Resektionsgrenzen liegen rechtsseitig des Lig. falciforme und auf der oft schwierig zu identifizierenden Grenze zwischen den Segmenten 5/6 so…
Trends in colorectal cancer incidence: a period and birth-cohort analysis in a well-defined French population.
2011
Abstract Background France stands among high-risk areas for colorectal cancer. Different trends in CRC incidence are reported around the world. The aim of this study was to provide temporal trends in CRC incidence over a 30-year period in a French well-defined population. Methods Between 1976 and 2005, 17,028 new cases were registered by the Burgundy digestive cancer registry. The mean variations in age-standardized incidence rates were estimated using a Poisson regression adjusted for age for each gender and location. The cumulative risk by birth cohort of developing a cancer over the age range 0-74 years was estimated using an age-cohort model. Results Incidence rates for right and left c…
Selective approach for upper rectal cancer treatment: total mesorectal excision and preoperative chemoradiation are seldom necessary.
2015
The implementation of preoperative chemoradiation combined with total mesorectal excision has reduced local recurrence rates in rectal cancer. However, the use of both types of treatment in upper rectal cancer is controversial.The purpose of this work was to assess oncological results after radical resection of upper rectal cancers compared with sigmoid, middle, and lower rectal cancers and to determine risk factors for local recurrence in upper rectal cancer.This was a retrospective analysis of prospectively collected data.This study was conducted in a tertiary care referral hospital in Valencia, Spain.Analysis included 1145 patients who underwent colorectal resection with primary curative…
Mesenteric Lymph Node Involvement in Advanced Ovarian Cancer Patients Undergoing Rectosigmoid Resection: Prognostic Role and Clinical Considerations
2014
Background: The aim of this retrospective study was to investigate the incidence of mesenteric lymph node (MLN) involvement, and its prognostic role in advanced ovarian cancer (OC). Methods: OC patients undergoing rectosigmoid resection during primary debulking surgery or interval debulking surgery were recorded. Progression-free survival (PFS) and overall survival were calculated from the date of diagnosis to the date of relapse/progression, death of disease, or the date of last follow-up. Results: MLNs were detected in 102/148 cases (68.9 %); the rate of MLN involvement was 47.0 %. The percentage of metastatic MLNs was higher in cases with >5 MLNs removed compared with cases with ≤5 MLNs …
A systematic review and meta-analysis comparing surgical and oncological outcomes of upper rectal, rectosigmoid and sigmoid tumours.
2021
Abstract Aim Management paradigms for tumours from the sigmoid colon to the lower rectum vary significantly. The upper rectum (UR) represents the transition point both anatomically and in treatment protocols. Above the UR is clearly defined and managed as colon cancer and below is managed as rectal cancer. This study compares outcomes between sigmoid, rectosigmoid and UR tumours to establish if differences exist in operative and oncological outcomes. Methods Electronic databases were searched for published studies with comparative data on peri-operative and oncological outcome for upper rectal and sigmoid/rectosigmoid (SRS) tumours treated without neoadjuvant radiation. The search adhered t…
